STUDIES OF OBSERVED AND PREDICTED VALUES OF BOTTOM REFLECTIVITY AS A FUNCTION OF INCIDENT ANGLE,

Abstract

A study has been instituted in an attempt to predict the reflection coefficient of particular bottom areas based on sediment core analysis and then compare these predicted data with the results of controlled acoustic measurements. The ocean bottom is an important factor in acoustic propagation through the ocean. To achieve this objective a theoretical model was developed in which the ocean is represented as a system of plane parallel layers of varying acoustic impedance; bottom roughness is not a factor in this model. The input parameters to the model consist of the results of analysis of bottom sediment cores obtained in the immediate area of the acoustic measurements. (Author)
